Solution

1. Make sure you're running SCCM with SP2 installed. If not, check out: http://support.microsoft.com/kb/957065 and http://support.microsoft.com/kb/971413

2. Try to refresh the package's distribution point (refresh, not update): Site Management --> Computer Management --> Operating System Deployment --> Operating System Install Packages --> PACKAGE_NAME --> Distribution Points --> Right click on the Distribution Point you're using and choose "Refresh Distribution Point"

3. If it doesn't work, try to remove the distribution completely and re-add it (you must WAIT for it to complete the removal before re-adding it, you can use the Package Status to make sure it was removed)

4. If all else fails, go to Site Management --> Computer Management --> Software Distribution --> Advertisements --> Right click on the task sequence advertisement you're deploying and choose "Properties" --> Distribution Points --> check "Access content directly from a distribution point when needed by the running task sequence".
